a cost that includes both fixed and variable cost components is called a: multiple choice mixed cost. step…

Brief Explanations:

A mixed cost has both fixed and variable elements. Fixed cost remains constant within a relevant range (e.g., base rent for a store). Variable cost changes with activity level (e.g., utility cost based on usage). Step - variable cost changes in steps (e.g., hiring an extra worker when production reaches a certain level). Composite cost is not a standard term in cost accounting. Incremental cost is the additional cost from a decision (e.g., cost of producing one more unit). Differential cost is the difference in cost between two alternatives.

Answer:

Mixed cost.
